Ukulele help? Lol

So I accidentally tuned one of my strings too high and now it won’t stay in the bridge as it’s a little chipped, I’ve tried tying a bigger knot at the end of the string, but I still can’t really tune it high enough to be in normal pitch. could I super glue it to keep it in place? Or is there anything I could do to fix it other than get a new uke? It’s a mahalo uke if that matters/helps
